Chemical Bonding and Molecular Structure - Result Question 81
####83. Which one of the following has the shortest carbon carbon bond length ?
[1992]
(a) Benzene
(b) Ethene
(c) Ethyne
(d) Ethane
Show Answer
Solution:
- (c) The bond length decreases in the order $s p^{3}>s p^{2}>s p$.
Because of the triple bond, the carbon-carbon bond distance in ethyne is shortest.
